Advanced search

Advanced search is divided into two main parts, and one or more groups in each of the main parts. The main parts are the "Search for" (including) and the "Remove from search" (excluding) part. (The excluding part might not be visible until you hit "NOT" for the first time.) You can add new groups to both the including and the excluding part by using the buttons "OR" or "NOT" respectively, and you can add more search options to all groups through the drop down menu on the last row (in each group).

For a result to be included in the search result, is it required to fit all added including parameters (in at least one group) and not fit all parameters in one of the excluding groups. This system with the two main parts and their groups makes it possible to combine two (or more) distinct searches into one search result, while being flexible in removing results from the final list.

Limit the search further

Here you can limit your search further, your result list will only contain those who match all of the criteria that you fill out in this part (combined with the advanced search from above)

Abstract [en]

Earlier studies refer to the fact that scientific research is lacking when it comes to functional training such as core strengthening and trunk stability in relation to athletic performance like throwing velocity. It is widely debated if instability when performed training exercises improves stability which in turn would improve athletic performance. The most equivalent study that has been made concerning training program with slings to improve trunk stability with the purpose to improve throwing velocity has shown significant results.

The purpose of this study was to investigate if six weeks core stability training program with the functional training equipment Func.Gym training bands improved the throwing velocity in male elite handball players.

Two groups were used in this study, one test group consisting of six subjects (n=6) with an average age of 22,3 years, and one control group consisting of three subjects (n=3), with an average age 21 years. All the subjects were team players from HK Drott.

The training program consisted of six exercises and was accomplished by the functional training equipment Func.Gym training bands.

To measure throwing velocity a Casio EX-F1 EXILIM was used, adjusted to high speed (hs) with 300 frames per second (fps). The clip from the high speed camera was analyzed in the Dartfish classroom edition program.

One of the test persons in the test group showed improved result in throwing velocity. The remaining, both test group and control group, showed decreased measures in velocity after six week training. Measures of exercise repetitions and questionnaire showed improved strength in trunk stability.

Conclusion: Func.Gym Training bands improved trunk stability but did not in this study show any positive effect on throwing velocity.
